SLC5A2 and hydrops fetalis: The GFR dip after SGLT2 inhibition was comparable in the two study subgroups, but a more prominent HF hospitalization (HFh) rate decline was present among subjects with HF at baseline (HR 0.51; 95% CI: 0.34–0.76 vs. HR 0.62; 95% CI: 0.35–1.10), while overall mortality was consistently affected in both subgroups (HR 0.56; 95% CI: 0.34–0.93 vs. HR 0.73; 95% CI: 0.54–0.97) [33] (Supplementary Table S1).
